Answer:

The slope of the line that intersects the points (13, -4) and (1, 12) is 4/-3.

Step-by-step explanation:

The equation m=\frac{y2-x2}{y1-x1} is used to solve for slope m.

m=\frac{12-(-4)}{1-13}=\frac{12+4}{-12} =\frac{16}{-12} =\frac{4}{-3}

If you need it in decimal form, then 4/-3=-1.33333333333

Sati [7]

Answer:

The profit of the bakery for this batch of rolls is C. $ 132

Step-by-step explanation:

You know the following this about the problem:

  • xy=300 is the total cost of the production of the rolls, where x is the cost of the rolls and y is the number of rolls.
  • Day 1 the bakery sold 4/5 of the rolls at 1.50 its value.
  • Day 2 the bakery sold 1/5 of the rolls ar 0.8 of the price of Day 1.

Day1=1.50x\frac{4}{5}y=\frac{3}{2}x\frac{4}{5}y=\frac{6}{5}xy\\Day2=0.8\frac{3}{2}x\frac{1}{5}y=\frac{4}{5}\frac{3}{2}x\frac{1}{5}y=\frac{6}{25}xy

The total gain of the sales is:

Day 1 + Day 2

Day1+Day2=\frac{6}{5}xy+\frac{6}{25}xy=\frac{36}{25}xy

and you know that xy =300, then the total gain is:

gain=\frac{36}{25}(300)=432

And the profit is the total gain less the total cost:

Profit = 432-300=132

Elden [556K]

Answer: $153.17

Step-by-step explanation:

85+85=$170

15% of $170 is $25.50.

170-25.50= $144.50

6% of 144.50=$8.67

144.50+8.67= $153.17

So, the answer is (B)-$153.17
